4. Write definitions for the following two functions: sumN (n) returns the sum of the first n natural numbers. sumNCubes (n) returns the sum of the cubes of the first n natural numbers. Then use these functions in a program that prompts a user for ann and prints out the sum of the first n natural numbers and the sum of the cubes of the first n natural numbers.

Write a program that calculates the Euclidean distance and the Manhattan or taxicabdistance between two two-dimensional points. Make sure you 1) use a point structureto store the points (see above), 2) use functions to calculate the two distances and3) ask the user for the point data. The Euclidean distance is calculated using thePythagorean Theorem for (points (x1,y1),and (x2, y2):euclidean = ( x1-x2)^2 + ( y1-y2)^2And the Manhattan distance is calculated as:manhattan = | x1-x2 | + | y1-y2 |
Write the following function to draw a regular polygon:def drawPolygon(x = 0, y = 0, radius = 50, numberOfSides = 3):The polygon is centered at (x, y) with a specified radius for the bounding circle for the polygon and the number of sides. Write a test program that displays a triangle, square, pentagon, hexagon, heptagon, and octagon, as shown in Figure 6.12a.
In Python: can you this problem be solved without using "while" and "for". Write a function called is_prime that receives a single integer value between 1 and 50 determines whether or not the integer is a prime. To determine if a number less than 50 is prime, you only need to divide it by all prime numbers less than or equal to the square root of 50 (i.e., 2, 3, 5, and 7). If any of them are smaller than the number and evenly divide the number, then it is not prime. By definition, 1 is not prime. Your solution should use the guess-and-check pattern. Write a main() function in your file to exercise your function to show that it works correctly. Your test implementation should not rely on visual inspection to determine if the tests pass.

"" Hosoya triangle (originally Fibonacci triangle) is a triangular arrangement of numbers, where if you take any number it is the sum of 2 numbers above. First line is always 1, and second line is always {1 1}. This printHosoya function takes argument n which is the height of the triangle (number of lines). For example: printHosoya( 6 ) would return: 1 1 1 2 1 2 3 2 2 3 5 3 4 3 5 8 5 6 6 5 8 The complexity is O(n^3). """ def hosoya(height, width):.
Write a program that computes the number of extraterrestrial civilizations capable of communicating with us. - The program should use the following as constants in accordance with Drake's calculations: R. = 1, f = 1, f₁ =1 - The program should prompt the user for the values of every other variable and store those variables as a data-type that makes sense given the type of information that the variable represents. - The program should compute the number of civilizations, N, and write this value to the console window.
In python An emirp is a nonpalindromic prime number whose reversal is also a prime. For example, 17 is a prime, and 71 is a prime, so 17 and 71 are emirps. Write a function that displays the first n emirps, display 10 numbers per line. displayEmirps(n), where n – is the number of palindromic prime numbers to display Prompt the user to enter how many numbers to display.
In C++ write a program that generates three random numbers and then find the min number among the generated values, using these three functions: void getrandnum(int &n1, int &n2, int &n3), int findMin(int n1, int n2, int n3), and void printResult(int n1, int n2, int n3, int min). Make the main function drive all these functions.
Three numbersa. Write a program that reads three numbers and prints “all the same” if they are allthe same, “all different” if they are all different, and “neither” otherwise.b. Write a program that reads three numbers and prints “increasing” if they are inincreasing order, “decreasing” if they are in decreasing order, and “neither”otherwise. Here, “increasing” means “strictly increasing”, with each value largerthan its predecessor. The sequence 3 4 4 would not be considered increasing.c. Repeat part b. but before reading the numbers, ask the user whetherincreasing/decreasing should be “strict” or “lenient”. In lenient mode, thesequence 3 4 4 is increasing and the sequence 4 4 4 is both increasing anddecreasing
6. Write a program which reads string and rewrite it in alphabetical order. For example, the word STRING should be written as GINRST. 7. Write a program to replace a particular word by another word in a given string. For example the “PYTHON” should be replaced by “C” in the text “It is good to program in PYTHON language”. 8. Write a program that will find the maximum number from 3 float type numbers. You have to usethe function getMax which will take 3 pointer variables and return the maximum number.
